[0002] The vibrating rod is a kind of machine used in engineering construction. It can remove bubbles in concrete when vibrating, make the concrete dense, eliminate the honeycomb surface of concrete and other phenomena, and improve the strength. When the vibrating rod is running, the vibrating tube is inserted into the concrete, and the bubbles mixed in the concrete are driven out by the vibration of the vibrating rod inside the vibrating tube, which plays a role in improving the strength of the concrete.

DETAILED DESCRIPTION

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Embodiment 1, this embodiment aims to provide a shock-absorbing small handheld concrete vibrator device, which is mainly used for the modification of the structure of the vibrator. The existing vibration rod structure has a relatively simple shock-absorbing structure, which is generally shock-absorbing through a spring and a damping structure. This shock-absorbing method is relatively single and has a poor shock-absorbing effect.

[0025] like Figure 5 As shown in the figure, the vibration collection mechanism includes a collection plate 4, a lower transmission rod 5 and a vibration plate 6; the collection plate 4 is fixed to the upper end of the connecting sleeve 2 and extends to the outer side. During implementation, the collection plate 4 can be a circular plate structure, the motor 3 is fixed on the first fixed plate 31, and a through hole is provided on the first fixed plate 31. The lower transmission rod 5 passes through the through hole and is fixed to the lower part of the vibration plate 6; the first fixed plate 31 serves as a fixing base of the motor 3. In order to ensure the stability of the motor 3, during implementation, the through hole is larger than the lower transmission rod 5 to prevent the vibration of the lower transmission rod 5 from being transmitted to the first fixed plate 31, thereby affecting the operation of the motor 3.

[0026] The vibration feedback mechanism includes a vibration collection sensor 7; the vibration collection sensor 7 is arranged on the vibration plate 6, and is used to collect the vibration data generated by the vibration rod; the connecting sleeve 2 receives the vibration of the vibration head 1 and uploads it to the vibration plate 6; in order to implement the collection of the vibration of the vibration plate 6, this embodiment monitors the implementation status of the vibration plate 6 through the vibration collection sensor.

[0029] A through hole is provided on the second fixed plate 8, and the upper end of the upper transmission rod 10 is fixed on the reaction plate 9 and can pass through the through hole.

By correspondingly configuring the upper transmission rod 10 and the lower transmission rod 5, the vibration amplitude generated by the electromagnetic vibrator 14 will directly act on the vibration plate and correspond to the lower transmission rod 5, so that the vibration and the reaction vibration correspond to each other.

[0032] In structure Figure 5 As shown in the figure, the vibration collection sensor 7 is arranged in the upper middle part of the vibration plate 6, the electromagnetic vibrator 14 is arranged below the second fixed plate 8, and an equipment box 15 and a handle 17 are arranged on the second fixed plate 8.

Data analysis The vibration spectrum analysis algorithm built into the control system processes the received vibration data and analyzes the frequency distribution of the vibration. When it is detected that the vibration amplitude exceeds the preset threshold, the control system automatically adjusts the working state of the vibration reduction module and generates a reduction vibration to reduce the impact of the vibration. After testing, this system can achieve 80% vibration reduction effect.
